I am towing a 16ft BT, Tare 2400, ATM 3300 with a series 9 (2015) GU Patrol. The vehicle has had a 3 inch exaust and chip installed to increase power and a GVM upgrade to 3495 kg to be legal when towing as I have a heavy vehicle with drawers, fridge, bull bar and winch, recovery equipment and tools.

I travel at 90 to 95 kph to help with fuel consumption which varies between 18 and 22 litres per 100 km on average depending on hilly and level roads. Greater fuel consumption on flat roads. The vehicle slows considerably when tackling steep roads.

My only real issue is a loss of power some times when towing, possibly caused by the difference between the vehicle and BT lights. The BT uses LED lights. I may need to have resisters fitted to the wiring to resolve the issue.

I should have been a little clearer. By loss of power, I meant a sudden loss of acceleration and throwing 3 fault codes dealing with fuel supply and bringing on the anti skid light. It was the dealer that suggested the resisters as they could not find any faults with the fuel system.

The loss of power is intermittent so hard to trace when everything looks ok when the dealer is checking for a cause. I hope this clears it up a little.

No offence here, but you left out the crucial component, the transmission.. That or after a few wines in Tasmania on Holiday, I missed it...
The Manual version of the Nissan is acceptable, going to 3200 kg towing capacity from memory... The Auto version, is weaker, only going to a limit of 2500 kg from memory.. Anyway, look at your towing capacity, and that will cap your size, to maybe 16' with the auto, or with the manual and if you want to load it up maybe the 18' size..

We have towed our 20' BT all over Aus in the last 10 years without a problem (2007 van and 2007 crd manual) . Bit slow up steep hills but still goes anywhere and we are not in a hurry. Have just swapped it for a Y62 V8 so now we fly up any hill. LOL_________________Bob & Laurel

Bob, couple of points of interest, for me anyhow,
What is the weight of the van in travel trim, and the weight of the Y62 in travel trim.
and what do you get fuel consumption wise in the Y62?_________________The Wandering Rosiebears...

Just completed a trip of 6500k's with about 400k of that touring without the van and averaged 19.5 l/h for the trip. Worst was into a big headwind across the hay plain at 22.5 l/h cruise control on 95
We travelled fairly light this trip with car at around 3300kg and van at around 3400kg with full tanks which we fill whenever possible._________________Bob & Laurel
